MS-ISAC CYBERSECURITY ADVISORY - Multiple Vulnerabilities in VMware vROP Could Allow for Arbitrary Code Execution - TLP: WHITE

MS-ISAC ADVISORY NUMBER:

2020-064

DATE(S) ISSUED:

05/11/2020

OVERVIEW:

Multiple vulnerabilities have been discovered in VMware’s vRealize Operations Manager (vROP), the most severe of which could allow for arbitrary code execution. These vulnerabilities are due to SaltStack being a component of vROP since version 7.5. Salt is an open-source remote task and configuration management framework widely used in data centers and cloud servers. Successful exploitation of the most severe of these vulnerabilities could result in arbitrary code execution. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If this application has been configured to have fewer user rights on the system, exploitation of the most severe of these vulnerabilities could have less impact than if it was configured with administrative rights.

THREAT INTELLIGENCE:

There are reports of these vulnerabilities being exploited in the wild.

SYSTEMS AFFECTED:

  • vROP versions 7.5.0 to 8.1.0

RISK:

Government:
  • Large and medium government entities: HIGH
  • Small government entities: MEDIUM
Businesses:
  • Large and medium business entities: HIGH
  • Small business entities: MEDIUM
Home Users:
N/A

TECHNICAL SUMMARY:

Multiple vulnerabilities have been discovered in VMware’s vRealize Operations Manager, the most severe of which could allow for arbitrary code execution. The vulnerabilities are as follows:

  • Improper method call validation that could allow for Arbitrary Code Execution. (CVE-2020-11651)
  • Improper method path sanitization that could allow for Arbitrary Directory Access. (CVE-2020-11652)

Successful exploitation of the most severe of these vulnerabilities could result in arbitrary code execution on systems running vROP. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If this application has been configured to have fewer user rights on the system, exploitation of the most severe of these vulnerabilities could have less impact than if it was configured with administrative rights.

RECOMMENDATIONS:

  • Apply appropriate measures provided by VMware to affected systems immediately after appropriate testing.
  • Apply patches provided by VMware as soon as they are released.
  • Apply the Principle of Least Privilege to all systems and services.
  • Verify no unauthorized system modifications have occurred on system before applying patch.
  • Monitor intrusion detection systems for any signs of anomalous activity.
  • Unless required, limit external network access to affected products.
